Want to Create a FabLab in your Garage? Start by Joining your Hackerspace
For many hardware enthusiasts, it’s hard to stop imagining the possibilities of an almighty fablab in our garage — a glorious suite of machines that can make the widgets of our dreams. Over the years, many of us start to build just that, assembling marvelous workbenches for the rest of us to drool over. The question is: “how do we get there?”
Ok, let’s say we’ve got a blank garage. We might be able to pick up a couple of tools and just “roll with it,” teaching ourselves the basics as we go and learning from our mistakes. With enough …read more
FCC Introduces Rules Banning WiFi Router Firmware Modification
For years we have been graced by cheap consumer electronics that are able to be upgraded through unofficial means. Your Nintendo DS is able to run unsigned code, your old XBox was a capable server for its time, your Android smartphone can be made better with CyanogenMod, and your wireless router could be expanded far beyond what it was originally designed to do thanks to the efforts of open source firmware creators. Now, this may change. In a proposed rule from the US Federal Communications Commission, devices with radios may be required to prevent modifications to firmware.
The proposed rule …read more
Before Arduino There was Basic Stamp: A Classic Teardown
Microcontrollers existed before the Arduino, and a device that anyone could program and blink an LED existed before the first Maker Faire. This might come as a surprise to some, but for others PICs and 68HC11s will remain as the first popular microcontrollers, found in everything from toys to microwave ovens.
Arduino can’t even claim its prominence as the first user-friendly microcontroller development board. This title goes to the humble Basic Stamp, a four-component board that was introduced in the early 1990s. I recently managed to get my hands on an original Basic Stamp kit. This is the teardown and …read more
Learning Verilog for FPGAs: Hardware at Last!
Getting into FPGA design isn’t a monolithic experience. You have to figure out a toolchain, learn how to think in hardware during the design, and translate that into working Verliog. The end goal is getting your work onto an actual piece of hardware, and that’s what this post is all about.
In the previous pair of installments in this series, you built a simple Verilog demonstration consisting of an adder and a few flip flop-based circuits. The simulations work, so now it is time to put the design into a real FPGA and see if it works in the real …read more
Ubuntu Core Supports Raspberry Pi 2 I/O
Although it isn’t official, Ubuntu Core–the tiny Internet of Things version of Ubuntu–now runs on the Raspberry Pi 2. There are prebuilt binaries as well as instructions for how to roll your own, if you prefer. You can even access GPIO
Ubuntu Core abandons the old-style Debian packages, in favor of Snap, a new version of the Ubuntu phone’s Click package manager. Snap offers transactional updates. The idea is that all of these “things” on the IoT need to be updated to patch security holes or fix other issues. …read more
